Automatic Signal Identification Function (Auto Id) - Promax TV EXPLORER HD ISDB-T Manual

In the External power supply mode is the unit powering the amplifiers before the
antenna (terrestrial television) or the satellite TV receiver (house-hold or community)
also powers the external units.
The DRAIN [3] indicator lights when current is flowing to the external unit. If any
kind of problem occurs (e.g., a short circuit), an error message appears on the monitor
('SUPPLY SHORT'), the acoustic indicator will be heard and the instrument will cease to
supply power. The TV EXPLORER
operating state until the problem has been solved, during this time it verifies every three
seconds the persistence of the problem warning with an acoustic signal.

Automatic signal identification function (AUTO ID)

The TV EXPLORER
according to the established configuration, which are presents in the channel or tuned
frequency. In order to activate this function must once press
useful, is to combine this process with the spectrum monitoring
locating the marker on the levels susceptible to contain a transmission, and activating
later the process of automatic identification in order to identify the present signal.

First it recognises whether the signal is an analogue channel or a digital one. If the
channel is analogue, it determines the television standard of the signal. When the signal
is digital (ISDB/DVB), it analyses for each modulation type QAM / QPSK / 8PSK /
ISDB-T/T all the associated parameters such as the modulation system: symbol rate,
B
code rate, etc.,. and determines the value of the signals under test.
If the AUTO ID function is launched in the spectrum analyser mode, the name of
the network will appear temporarily on screen (it also appears in the measurement
display). In case of working in the satellite band the orbital position appears as well.
